Digital LCD Display: Easy to read LCD display provides clear digital reading. The power meter continuously provides real-time reading of amps, volts and watts after connection. Provides 8 electrical readings: current (A), voltage (V), watts (W), amp-hours (Ah), watts -hours (Wh), peak amps (Ap), minimum volts (Vm), peak watts (Wp). High accuracy: 0-150 amps measurement, 0.01 amps resolution. Measures 0-60 volts, resolution 0.01 volts. 0 - 6554W, 0.1W resolution. 0 - 65Ah, resolution 0.001Ah. 0 - 6554Wh, resolution 0.1Wh. Multifunctional tool: check whether the working voltage is sufficient under load. Prevent surge current from damaging batteries, controller, motors, wiring and connectors. Check that the battery charger is working properly (connect battery and charger). Function: Individual cells are balanced. Set the cut-off voltage and check the battery capacity. Detect the receiver and the actual working current to determine whether UBEC, etc. The product encounters quality problems within the year. We will provide free after-sales service maintenance or replacement. Note: The data are all manual measurement, please allow 1-3cm error, due to the difference in light and d display, there will be some color difference, depending on the physical object received.
